In order to meet the requirement of deeply limiting the operating overvoltage level of a 500 kV AC power system, a controllable metal oxide surge arrester with a trigger switch was developed. The key ...

Metal oxide surge arresters are of great significance for surge arrester configuration, insulation coordination research, and system reliability calculation. Their accurate modeling depends on precise ...

The digital algorithms presently available for on-line monitoring of metal oxide surge arrester (MOA) are normally based on a simplified equivalent model consisting of a capacitor and a nonlinear ...

In the simulation of very fast transient over-voltage (VFTO), establishing the accurate equivalent model of electrical equipments in GIS has a major effect on the calculation results. At present, ...
